Flash-lag effect: complicating motion extrapolation of the moving reference-stimulus paradoxically augments the effect

One fundamental property of the perceptual and cognitive systems is their capacity for prediction in the dynamic environment; the flash-lag effect has been considered as a particularly suggestive example of this capacity (Nijhawan in nature 370:256-257, 1994, Behav brain sci 31:179-239, 2008). Thus, because of involvement of the mechanisms of extrapolation and visual prediction, the moving object is perceived ahead of the simultaneously flashed static object objectively aligned with the moving one. In the present study we introduce a new method and report experimental results inconsistent with at least some versions of the prediction/extrapolation theory. We show that a stimulus moving in the opposite direction to the reference stimulus by approaching it before the flash does not diminish the flash-lag effect, but rather augments it. In addition, alternative theories (in)capable of explaining this paradoxical result are discussed.     

Enhancing effects of acute psychosocial stress on priming of non-declarative memory in healthy young adults

Social stress affects cognitive processes in general, and memory performance in particular. However, the direction of these effects has not been clearly established, as it depends on several factors. Our aim was to determine the impact of the hypothalamus-pituitary-adrenal (HPA) axis and sympathetic nervous system (SNS) reactivity to psychosocial stress on short-term non-declarative memory and declarative memory performance. Fifty-two young participants (18 men, 34 women) were subjected to the Trier Social Stress Task (TSST) and a control condition in a crossover design. Implicit memory was assessed by a priming test, and explicit memory was assessed by the Rey Auditory Verbal Learning Test (RAVLT). The TSST provoked greater salivary cortisol and salivary alpha-amylase (sAA) responses than the control task. Men had a higher cortisol response to stress than women, but no sex differences were found for sAA release. Stress was associated with an enhancement of priming but did not affect declarative memory. Additionally, the enhancement on the priming test was higher in those whose sAA levels increased more in response to stress (r(48)?=?0.339, p?=?0.018). Our results confirm an effect of acute stress on priming, and that this effect is related to SNS activity. In addition, they suggest a different relationship between stress biomarkers and the different memory systems.     

Res Computans: The Living Subject from Yeast to Human

Since modernity, the concept of subject supposes both an anthropocentric and a dualistic view of life and reality. In this study, we carry out an analytic interpretation of the Descartes’ notion of subject, in order to build a different dimension of the concept of subject. We discuss the activity of computing, as the manner by which the living subject relates with and in-forms the world. We further examine computing in the aging yeast as an example of living subject and we try to comprehend the maturity of the subjectivity in Descartes’ res cogitans and in our proposed res computans.     

From multimodal programs to a new cognitive–interpersonal approach in the rehabilitation of offenders

A considerable amount of meta-analytic research supports the effectiveness of cognitive–behavioral psychoeducational programs in reducing recidivism rates, in youths and adults with antisocial behavior. These same studies suggest that programs including a cognitive component are as twice as more effective in reducing recidivism rates. This paper reviews outcome studies sustaining the use of structured interventions in forensic settings. It introduces a new program, Growing Pro-Social (GPS), currently in use in several Portuguese youth rehabilitation centers and prisons. GPS is a multimodal structured group program designed for the rehabilitation of individuals with antisocial behavior. It includes 40 weekly sessions, organized into 5 sequential modules. Based on a cognitive–interpersonal theoretical framework, GPS focuses on cognitive, emotional, and behavioral change, assuming as an ultimate goal the modification of dysfunctional core beliefs underlying antisocial behavior.     

Organizational justice and extrarole customer service: The mediating role of well-being at work

The purpose of this article is to propose and test a model of extrarole customer service (ERCS). We propose that organizational justice (distributive, procedural, interpersonal, and informational) promotes well-being at work (low burnout and high engagement). Well-being at work, in turn, engenders more effective ERCS. Thus, well-being at work is considered a mediator of the relationships from organizational justice to ERCS. This fully mediated model was compared to an alternative fully direct model. The sample consisted of 317 contact employees who were working in the Spanish service sector. The results of structural equation modelling supported the importance of the mediating role of the positive side of well-being at work (engagement) in the relationship between organizational justice and ERCS. The article concludes with a discussion of the theoretical and managerial implications.     

How Has the Economic Downturn Affected Communities and Implementation of Science‐Based Prevention in the Randomized Trial of Communities That Care?

This study examined implications of the economic downturn that began in December 2007 for the Community Youth Development Study (CYDS), a longitudinal randomized controlled trial of the Communities That Care (CTC) prevention system. The downturn had the potential to affect the internal validity of the CYDS research design and implementation of science-based prevention in study communities. We used archival economic indicators and community key leader reports of economic conditions to assess the extent of the economic downturn in CYDS communities and potential internal validity threats. We also examined whether stronger economic downturn effects were associated with a decline in science-based prevention implementation. Economic indicators suggested the downturn affected CYDS communities to different degrees. We found no evidence of systematic differences in downturn effects in CTC compared to control communities that would threaten internal validity of the randomized trial. The Community Economic Problems scale was a reliable measure of community economic conditions, and it showed criterion validity in relation to several objective economic indicators. CTC coalitions continued to implement science-based prevention to a significantly greater degree than control coalitions 2 years after the downturn began. However, CTC implementation levels declined to some extent as unemployment, the percentage of students qualifying for free lunch, and community economic problems worsened. Control coalition implementation levels were not related to economic conditions before or after the downturn, but mean implementation levels of science-based prevention were also relatively low in both periods.     

Sleep deprivation effects on object discrimination task in zebrafish (<Emphasis Type="Italic">Danio rerio</Emphasis>)

The zebrafish is an ideal vertebrate model for neurobehavioral studies with translational relevance to humans. Many aspects of sleep have been studied, but we still do not understand how and why sleep deprivation alters behavioral and physiological processes. A number of hypotheses suggest its role in memory consolidation. In this respect, the aim of this study was to analyze the effects of sleep deprivation on memory in zebrafish (Danio rerio), using an object discrimination paradigm. Four treatments were tested: control, partial sleep deprivation, total sleep deprivation by light pulses, and total sleep deprivation by extended light. The control group explored the new object more than the known object, indicating clear discrimination. The partially sleep-deprived group explored the new object more than the other object in the discrimination phase, suggesting a certain degree of discriminative performance. By contrast, both total sleep deprivation groups equally explored all objects, regardless of their novelty. It seems that only one night of sleep deprivation is enough to affect discriminative response in zebrafish, indicating its negative impact on cognitive processes. We suggest that this study could be a useful screening tool for cognitive dysfunction and a better understanding of the effect of sleep-wake cycles on cognition.     

Validation of Dating Violence Questionnarie-R (DVQ-R)

Background/Objective

Despite the growing interest in the study of dating violence, relatively few psychometrically sound instruments are available to researchers. To provide an instrument to researchers and professionals to assess victimization in dating relationships, with adequate psychometric properties. Method: Participants were 6,138 adolescents drawn from the general population, 25% of which were university students. Participants responded to the original Dating Violence Questionnaire (DVQ). Results: Confirmatory analyses results provided evidence of a clear factorial structure that was invariant through sex groups. The DVQ-R measures with 20 items five dimensions of abuse in affective interpersonal relationships of adolescents and youth: Detachment, Humiliation, Coercion, Physical and Sexual violence. Internal consistency indexes were adequate for both each one of the five dimensions as well as for the general scale. Conclusions: The DVQ-R is an useful assessment to be applied in adolescents and youth. Implications for research and intervention are discussed in light of the results obtained.
